VEHICLE-DUMP.

Specification of Letters Patent.

Application led September 24, 1913. Serial No. 791,455.

To all whom. 'it may concern.'

Be it known that "I, CHRISTOPHER L. AYeAixN, uv citizen of the UnitedStates, and a resident of the city of Seneca, county of La v'alle, andState of Illinois, have invented certain new andvu'seful Improvements inVehicle-Dumps, of which the following is a specification.

My invention relates to improvements 'in vehicle dumps and has for itsobject the provision of an improved .construction of this character'which is safe and eflicient in operation.

A furtherobject of the invention is to provide a vehicle dump adaptedfor use in dumping wagons or sleighs.

The invention consistsin the combinations and arrangements ofpartsscribed and claimed.'

The invention will be best understood by reference to the' accompanyingdrawings forming apart of this specification, and in Y Figure 1 is aside view of a vehicle dump embodying my invention, Fig. 2, a top planview ofthe' seme, Fig. 3, a bottom prlan view corresponding toFig'. 2,Fig. 4, an en largcd -section taken on line :l2-aref Fig. 2, and Fig.'5, an enlarged section taken on line 1 y of Fig. 2.

The preferred form of construction as illustrated in the drawingscomprises a supportingA platform 1 of any usual or desired constructionandl adapted to permit driving of-a teamrthereon. Arranged in platform 1is ai'pair of wheel tracks 2 and 3 which are 'connected together attheir forward ends by ineansjof a cross platform l as indicated. Acnrvedsheet metal guard 4' is arranged at the forward end of platform 4'and is adapted to close the gap between the l forward end of saidplatform 4 and platform. 1 when the platfornrd is tilted or dumped Iasindicated in Fig. 1. Tracks 2 and 3 are pivoted for tilting or dumping'on a cross rod or shaft 5 arranged under `iso platform 1 and asupplemental sleigh dumping platform 6 is arranged within tracks 2 and 3and is also pivoted for tilting or dumping on shaft 5 independently oftracks 2 and 3. ,ik rock shaft 7 is arrangedacross the rear ends oftracks 2 and 3 and is bent to form crank arms 8 which are adapted torest under the rear ends of said tracks Aand support the-same fromtilting, said shaft being provided at one end with an operatinghereinafter de? Patented Dec. 8, 1914.

lever 9 Afor withdrawing saidferank arms from supporting position andpermitting the dumpingor tilting of tracks 2 and 3. A cross bar 10 isarranged across the rear ends of tracks 2 and 3 immediately under sleighplatform 6 and serves to prevent dumping or tilting of platform 6 whentracks 2 and 3 are supported but permits dumping of tracks 2 and 3independently of platform 6 as will Vbe readily understood.

Arranged at the rear of tracks 2 and 3 and platform 6 is an upwardlyswinging trap door 11 which is arranged to be swung upwardly to permitofthe discharge of grain under side a locking cam or projection 12.

which is adapted to engage a locking arm 13 on shaft 7 when'said trapdoor is depressed and hold said shaft/,from unlockingmovementhvthuspositively preventing tilting or dumping of the wheeltracks or sleigh platform w en said trap door is closed adding to thesafety of the construction.

Locking bolts or bars are slidably mounted on the under side ofplatfor'm1v inposition to project under each endof platform 6 and thus lock saidVplatform 6 from dump ing or tilting. Bars 14 are operatively connectedwith crunk arms 15 and 16 formed on an operating shaft 17 arranged onthe under sidev of platform 1 and provided with an operating lever 18'.ABy this arrangement it will be observed that by manipulating operatinglever 18, platform 6 may be freed for dumping with tracks 2 and 3. ormav be hcldfrom dumping therewith -ns desired.

.Arranged at the rear "end of track 2 is an upwardly swinging wheelvstop 19 which carries a stop bar 2O slidable in said wheel trackand-having a sto nut-21 at its lower end adapted to limit 't `e upwardswinging of said wheel stop. A lever 22 is arranged on the under .sideof wheel track 2 and is .provided 'at one endwith an upwardly exered orinoperative position and wheel rest -'as described.
